answer is supposed to be a mixed number??

thank you for helping

The area of shaded and unshaded sector is 1.13 × P^2 and 1.99 × P^2.

Find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object.

Suppose that radius of the considered sphere is of 'r' units.

Then, its surface area S would be:

[tex]S = 4\pi r^2 \: \rm unit^2[/tex]

We are given that;

P is the center, angle LPJ=130degree

Now,

To find the approximate values, we can use 3.14 for π and round to the nearest tenth:

Area of shaded sector = (13π/36) × P^2

≈ (13 × 3.14/36) × P^2

≈ 1.13 × P^2

Area of unshaded sector = (23π/36) × P^2

≈ (23 × 3.14/36) × P^2

≈ 1.99 × P^2

Therefore, by the surface area the answer will be 1.13 × P^2 and 1.99 × P^2.

Step-by-step explanation:

Quadrilateral JKLM is inscribed in a circle, so it is a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Answer:

3 hrs 38.2 min, Candle 2 will be three times the length of candle 1

Step-by-step explanation:

If Dora burns candles that burn for 4 and 5 hours they burn for 9 hours combined one after another.

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

here,
Dora has three candles, which will burn for 3, 4, and 5 hours,
The combination of the hours of burning,
3 + 4 = 7 hours
4 + 5 = 9 hours
3 + 5 = 8 hours

Thus, if Dora burns candles that burn for 4 and 5 hours they burn for 9 hours combined one after another.

Answer:

a = 25

Step-by-step explanation:

The exterior angles of a polygon sum to 360°

Sum the exterior angles and equate to 360

a + a + 40 + 51 + 55 + 54 + 2a + 60 = 360, that is

4a + 260 = 360 ( subtract 260 from both sides )

4a = 100 ( divide both sides by 4 )

a = 25

Answer:

The mass of the fifth player is 73 kg

Step-by-step explanation:

Since the average mass of the 5 players is 70kg

what this mean is that the total sum of all the masses of the players is equal to the product of 5 and 70 kg

we have this as 5 * 70kg = 350 kg

So, by adding the masses of all the players, we get 350kg

Thus, for us to get the mass of the 5th player, we have to subtract the sum of the remaining 4 from the total 350kg

Mathematically, we have this as;

350 - ( 50 + 62+ 81 + 84) = 73 kg

Answer:

Answer: $510

Step-by-step explanation:

Total monthly budget = $3,400.

Percentage of total budget spent on utilities = 15%

The amount that the Riddle Family spending on utilities each month will then be:

= 15% × $3400

= 15/100 × $3400

= 0.15 × $3400

= $510

Answer:

0.15 * 3400 = $________ utilities cost per month

Multiply the monthly cost by 12.

Step-by-step explanation:

If the question was "A mother bear and her cub catch fish from a river. The cub catches 10 fish and the mother bear catches 5 times as many as the cub. How many fish did the cub catch?" then the answer would be, The mother bear caught 50 fish.

This is because if the cub caught 10, and the mother caught 5 times that amount, the mother caught 5 x 10 fish. 5 x 10 = 50.

Answer:

x =30.7

Step-by-step explanation:

Here, we want to find the value of x

To get this, we use the appropriate trigonometric ratio

From what we have, we have the side facing an angle which is the opposite and the side not facing an angle or the right angle; this is the adjacent

The trigonometric identity that links the opposite and the adjacent is called the tan

It is the ratio of the opposite to the adjacent

Thus, we have;

tan 61 = x/17

x = 17 * tan 61

x = 30.7

Answer:

$131.85

Step-by-step explanation:

First, we need to find the net price (after discount and tax) It's a 15% discount, so just find 85% (100-15=85) of the original price. You'll get $373.15.

For tax, multiply by 1.06, since it's a 6% tax (1+.06). You'll get $395.539.

You're paying over 3 months time, so to find payment each month just divide by 3.

395.539/3 = 131.8463333

Round to 131.85

Your answer is $131.85 dollars per month

Answer:

See solution below

Step-by-step explanation:

According to the diagram shown

m<1 = m<5 = 5=65 degrees (corresponding angle)

m<5 = m<4 - 65 degrees (alternate interior angle)

m<9 = m<8 = 65degrees (corresponding angle)

m<5 = m<8 = 65dgrees (vertically opposite angles)

m<6+m<8 = 180

m<6 + 65 = 180

m<6 = 180 - 65

m<6 = 115degrees

m<2 = m<6 = 115degrees (corresponding angles)

m<6 = m<7 = 115degrees (vertically opposite angles)

m<3 = m<7 = 115degrees(corresponding angle)

)

The measures of the other seven angles are evaluated as:

[tex]m\angle 1 = 65^\circ = m\angle 5\\m\angle 2 =115^\circ = m\angle 6\\m\angle 3 =65^\circ = m\angle 7\\m\angle 4 = 115^\circ =m\angle 8[/tex]

Two angels whose sum is 180° are called supplementary angles.

When they are added together graphically, they form a straight line.

Each of the pairs of the opposite angles made by two intersecting lines are called vertical angles. They are of same measurement.

In literal sense, corresponding means pair wise angles. Like the right corner angles of two triangles etc. But usually we take them as:

For two similar figures, the pair by pair similar angles of those two similar figures are called corresponding angles. They are of same measurement.

For this case, we have:

Angle 1,2,3 and 4 corresponding to 5,6,7 and 8 angle respectively.  It is because the two lines A and B are parallel and the traversing line intersects both of them. When single line intersect two parallel lines, it makes same corresponding angles on both of the sides. That means

[tex]m\angle 1 = m\angle 5\\m\angle 2 = m\angle 6\\m\angle 3 = m\angle 7\\m\angle 4 = m\angle 8[/tex]

where that small 'm' denotes that we're taking about their measurements.

Thus, we will only find 1,2,3,and angle 4's measurements and rest four would be found.

Since angle 1 and angle 4 are vertical angles, they are same measurement. Since angle 1 is of 65 degrees, thus:

[tex]m\angle 1 = 65^\circ = m\angle 4[/tex]

Now, since angle angle 3 is supplementary to angle 1 and so as angle 2 to angle 4, thus:

[tex]m\angle 2 + m\angle 4 = 180^\circ\\m\angle 2 = 180-m\angle 4= 115^\circ\\\\m\angle 3 + m\angle 1 = 180^\circ\\m\angle 3 = 180-m\angle 1= 115^\circ[/tex]

Thus, we get the measurement of all angles as:

[tex]m\angle 1 = 65^\circ = m\angle 5\\m\angle 2 =115^\circ = m\angle 6\\m\angle 3 =65^\circ = m\angle 7\\m\angle 4 = 115^\circ =m\angle 8[/tex]
